What is the target oxygen saturation for a patient with COPD?

The target oxygen saturation for a patient with chronic obstructive pulmonary disease (COPD) is typically set at 88% to 92%. This range is important because it helps to ensure that the patient is receiving adequate oxygen without risking hyperoxia, which can occur if oxygen levels are too high. In patients with COPD, the drive to breathe can be more sensitive to carbon dioxide levels than to oxygen levels, and providing too much supplemental oxygen can potentially suppress their respiratory drive.

Maintaining saturation in the 88% to 92% range helps to minimize the risk of complications associated with both hypoxia and hyperoxia, promoting better overall respiratory functioning while avoiding exacerbations of their condition. In contrast, saturation levels below 88% could indicate inadequate oxygenation, while levels above 92% might lead to risks associated with excess oxygen.
